Driving Test Revision

DVSA Show Me, Tell Me Practice Quiz

During the practical car driving test, the examiner will ask one ‘tell me’ vehicle-safety question before the candidate starts driving and one ‘show me’ question while the candidate is driving. Answering one or both questions incorrectly normally results in one driving fault. Driving dangerously while carrying out the ‘show me’ task could result in a serious or dangerous fault.

This ALD practice quiz is designed to support revision. It is not an official DVSA test, and there is no separate DVSA pass mark for this quiz.

Always revise from the official list as well: Car ‘show me, tell me’ vehicle safety questions on GOV.UK.

Every question has three possible answers — A, B or C — and only one of them is correct. Your results and an explanation for every question are shown at the end. The show me section supports revision only: on test day the task must be demonstrated safely while you are driving.

Tell Me Study Guide — 14 questions

The examiner asks one of these vehicle-safety questions before you start driving.

Tell me how you'd check that the brakes are working before starting a journey.

Answer: The brakes should be tested as the vehicle sets off. They should not feel spongy or slack, and the vehicle should not pull to one side.

Test the brakes as you move off at low speed. The pedal should feel firm rather than spongy or slack, and the car should slow in a straight line without pulling to one side. A dashboard light alone does not prove the brakes work, and heavy braking at speed is neither necessary nor safe.

Tell me where you'd find the information for the recommended tyre pressures for this car and how tyre pressures should be checked.

Answer: The pressures are shown in the manufacturer's guide. Use a reliable pressure gauge, check and adjust the pressures when the tyres are cold, don't forget the spare where one is fitted, and refit the valve caps afterwards.

The recommended pressures are in the manufacturer's guide — often repeated on a label in the door shut or fuel filler flap. Use a reliable gauge, check and adjust the tyres while they are cold, include the spare if the car carries one, and replace the valve caps when you have finished.

Tell me how you make sure your head restraint is correctly adjusted so it provides the best protection in the event of a crash.

Answer: The rigid part of the head restraint should be at least as high as the eyes or the top of the ears, and as close to the back of the head as is comfortable. Some head restraints are not adjustable.

The rigid part of the restraint should sit at least level with your eyes or the top of your ears, and as close to the back of your head as is comfortable. Note that some head restraints are fixed and cannot be adjusted.

Tell me how you'd check the tyres to ensure that they have sufficient tread depth and that their general condition is safe to use on the road.

Answer: There should be no cuts or bulges, and the tread depth must be at least 1.6 mm across the central three-quarters of the breadth of the tyre and around the entire outer circumference.

Look over each tyre for cuts and bulges, then check the tread. The legal minimum is 1.6 mm across the central three-quarters of the tyre's breadth and around its entire outer circumference — on every tyre, not just the front ones.

Tell me how you'd check that the headlights and tail lights are working. You do not need to exit the vehicle.

Answer: Operate the light switch, turning on the ignition first if necessary, then walk round the vehicle to check that the headlights and tail lights are working.

Turn on the ignition if the car needs it, operate the correct light switch, and explain that you would walk around the vehicle to see that the headlights and tail lights are all working.

Tell me how you'd know if there was a problem with the anti-lock braking system.

Answer: A warning light would illuminate if there was a fault with the ABS.

An ABS warning light on the dashboard illuminates if there is a fault with the anti-lock braking system. If it stays on, the car should be checked before further driving.

Tell me how you'd check that the direction indicators are working. You do not need to exit the vehicle.

Answer: Apply the indicators or hazard warning switch and walk round the vehicle to check that all the indicators are working, or check the relevant tell-tale indicators.

Operate the indicators or the hazard warning switch, then explain that you would walk around the vehicle to confirm that each one flashes — or check the tell-tale indicators on the dashboard.

Tell me how you'd check that the brake lights are working on this car.

Answer: Operate the brake pedal and make use of reflections in windows or garage doors, or ask someone to stand behind the vehicle and check them.

Press the brake pedal and look for the reflected glow in a window, garage door or a wall behind the car — or ask somebody to stand safely behind the vehicle and confirm the lights come on.

Tell me how you'd check that the power-assisted steering is working before starting a journey.

Answer: If the power-assisted steering was broken, the steering would feel heavy. Gentle pressure on the steering wheel while the engine is started should produce noticeable movement as the system begins to operate, or the steering should respond normally as the vehicle begins to move.

Paul's simple way of remembering it: if the power-assisted steering was broken, the steering would feel heavy. Holding gentle pressure on the wheel as the engine starts should produce a slight but noticeable movement as the assistance takes over, or the steering should simply feel normal and light as the car starts to move.

Tell me how you'd switch on the rear fog lights and explain when you'd use them. You do not need to exit the vehicle.

Answer: Operate the switch, turning on the ignition and dipped headlights if required, and check that the warning light is illuminated. Use them only when visibility is seriously reduced — generally when you can see less than 100 metres.

Turn on the ignition and dipped headlights if the car requires it, operate the rear fog light control, and confirm the warning light is on. Rear fog lights must only be used when visibility is seriously reduced — generally less than 100 metres — and must be switched off when visibility improves.

Tell me how you'd switch your headlights from dipped to main beam and explain how you'd know the main beam is on.

Answer: Operate the main beam control, switching on the ignition or engine if necessary, and check that the blue main beam warning light on the dashboard is illuminated.

Turn on the ignition or engine if required, operate the headlight stalk to select main beam, and confirm it by the blue main beam warning light on the instrument panel.

Open the bonnet and tell me how you'd check that the engine has sufficient oil.

Answer: Identify the dipstick or the electronic oil level indicator, and check that the oil level is between the minimum and maximum markers.

Find the dipstick — or the electronic oil level display where the car has one — and check that the level sits between the minimum and maximum markings.

Open the bonnet and tell me how you'd check that the engine has sufficient engine coolant.

Answer: Identify the header tank, check the coolant level against the high and low markings when the engine is cold, and top up to the correct level if necessary.

Identify the coolant header tank and check the level against the high and low markings while the engine is cold, topping up correctly if needed. Never open a hot, pressurised cooling system — escaping steam and coolant can cause serious burns.

Open the bonnet and tell me how you'd check that you have a safe level of hydraulic brake fluid.

Answer: Identify the brake fluid reservoir and check that the fluid level is between the maximum and minimum markings.

Locate the brake fluid reservoir and check that the fluid sits between the minimum and maximum markings. A falling level can indicate wear or a leak and should be investigated.

Show Me Study Guide — 7 questions

The examiner asks one of these while you are driving. Carry the task out only when it is safe, and keep full control of the vehicle at all times.

When it's safe to do so, can you show me how you wash and clean the rear windscreen?

Answer: Keep proper control of the vehicle and, when it is safe, operate the control that washes and wipes the rear windscreen.

Stay in full control of the car, choose a safe moment, and operate the rear wash-wipe control. The examiner is checking that you can use the control without losing control of the vehicle.

When it's safe to do so, can you show me how you wash and clean the front windscreen?

Answer: Maintain proper control of the vehicle and, when it is safe, operate the control that washes and wipes the front windscreen.

Keep both eyes on the road and full control of the car, then operate the front washer and wiper control when it is safe to take a hand off the wheel briefly.

When it's safe to do so, can you show me how you'd switch on your dipped headlights?

Answer: Maintain proper control of the vehicle and operate the dipped headlight control when it is safe to do so.

Keep control of the car and operate the headlight switch to dipped beam at a safe moment. You should not need to look down for long or steer off course while doing it.

When it's safe to do so, can you show me how you'd set the rear demister?

Answer: Maintain proper control of the vehicle and operate the rear window demister control when it is safe to do so.

Stay in control of the car and press the heated rear window (rear demister) button when safe. It usually has its own warning light to confirm it is on.

When it's safe to do so, can you show me how you'd operate the horn?

Answer: Maintain proper control of the vehicle and press the horn control briefly at a safe and appropriate moment.

Keep control of the car and give the horn a short press when it will not alarm or mislead other road users — for example, not while stationary or in a built-up area at night unless there is danger.

When it's safe to do so, can you show me how you'd demist the front windscreen?

Answer: Maintain proper control of the vehicle and use the front demist control, or set the fan, temperature and airflow direction to clear the front windscreen.

Keep control of the car and either press the dedicated front demist button or set the fan speed, temperature and airflow direction towards the windscreen. Air conditioning, where fitted, clears the glass faster.

When it's safe to do so, can you show me how you'd open and close the side window?

Answer: Maintain proper control of the vehicle and operate the correct window control to open and then close the side window.

Stay in control of the car and use the correct switch to open and then close the side window at a safe moment, without becoming distracted from the road.
